Epic Mickey, Deus Ex Developer Worked on Half-Life

Warren Spector, Deus Ex creator and visionary for Disney Epic Mickey, contributed to Half-Life prior to Disney's acquisition of Junction Point Studios. Between 2005 and 2007 Spector and his studio worked with Valve on an unspecified Half-Life project, according to a Q&A discovered by Kotaku. Junction Point closed this past January.

Given the time frame, Junction Point's contributions could apply to the Half-Life 2 episodes, which released in 2006 and 2007. Arkane Studios, made up of other Deus Ex alumni, also appeared to have worked on a Half-Life episode called Return to Ravenholm.
